GRAIN-WEIGHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 375,163, dated December20, 1887.

application filed April 27, 1887. Serial No. 236,316. (No model.)

To all whom it may concern:

Be it known that I, GEORGE P. JAMESON, of Abingdon, in the county ofKnox and State of Illinois, have invented a new and Improved new'andimproved grain weighing and measuring machine which is simple anddurable in construction and very effective and automatic in operation.

The invention consists in the construction and arrangement of variousparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed out in they claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a side elevation of my improve ment attached to athrashing-machine. Fig. 2 is an enlarged side elevation of myimprovement, and Fig. 3 is an end elevation of part of the same.

My improvement is specially adapted for thrashing-machines which conveythe thrashed grain into a machine which, after automatically weighingand measuring the grain, delivers it to a wagon or other receptacle.

Myimprovemeut A is supported on an L- shaped arm, B, secured by the endof its vertical arm to the top of the thrashing-machine O in such amanner that my improvement hangs over the side of the thrashing-machineO and can be swung sidewise. On the outer end of the arm B is hung aspring weighingscale, D, of any suitable construction,and connected atits lower end with a U-shaped arm, E, in which 'is mounted to turn theshaft F, carrying the grain-weighing cylinder G,which consists of thetwo circular end plates, G ,con-

nected with each other by four radial partitions, G", extending at rightangles to each other, so as to form four equal compartments in thegrain-measuring cylinder G. The Weight of the latter and of the U shapedarm Eis supported by a lever, H, engaging with its front 7 end saidU-shaped'arm E, being fulcrumed on a U-shaped brace, I, secured to thebraces I O and 1 fastenedto the arm B.

On the inner end of the lever H is mounted adjustably the balance-weightH, which can be accurately set on said lever H to balance k thegrain-measuring cylinder G and its U- shaped arm E.

On the outside of the sides G of the grainmeasuring cylinder- G aresecured the four lugs G held near the rims of said sides G and midwaybetween the outer ends of the partitions G. The lugs G arealternatelyengaged by a hook, J, formed on the outer end of the lever J, fulcrumedon the brace I, and connected at its inner end with one end of a spring,K, secured by its other end to the U- shaped brace I. The position ofthe lever J can be regulated by a screw, L, engaging the top edge ofsaid lever J and screwing in a U- shaped keeper, L, pivoted to the brace1 the lever J passing through said keeper.

The lugs G are also alternately engaged on their other side by a hook,N, formed on the outer end of the arm N, pivoted on the lever J betweenits fulcrum on the brace I and its book J. On the under edge of the armN, near its fulcrum, is formed a transverse lug, N adapted to engage thelower edge of the lever. J, whereby said arm N is held in a horizontalposition in line with said lever J.

The grain-weighing cylinder G is prevented from moving sidewise andendwise by thelinks O, pivotally connected with the shaft F and with thelower ends of the braces 1 Into the compartments formed by thepartitions G in the weighing and measuring cylinder G opens the lowerend of the chute 1?, held in an upwardly-inclined position and supportedat its upper end by the link Q and the L-sh aped arm B, which isprovided with a pin, B, to prevent the link Qfrom slipping. Into thechute P opens a flexible chute, 0, connected with the upper end of thegrain-elevator G", into the lower end of which discharges the spout 0,extending from the graiubox of the thrashing machine 0..

The operation is as follows: The grain-weighing cylinder G stands in itsnormal position, as shown in Figs. 2 and 3, in which the partitions Gextend at an angle of forty-five degrees to the horizontal plane. Thechute P opens into the top compartment and the grain delivered from thethrashing-machine by the elevator G to the chute passes into the chute 5P and fills the upper compartment. The grainmeasuring cylinder G is heldin this position by the hooks J and N engaging the respect ive lugs G onthe sides G, of the cylinder G until the weight of the grain in thecompartro ment moves the parts of the spring-scale D so far apart thatthe grain-cylinder G is lowered until the hooks J and N disengage therespective lugs G The weight of the grain in the uppermost compartmeetthen causes the I 5 cylinder G to rotate, whereby the grain in saidcompartment is emptied into the wagon or other receptacle standing belowthe grainweighing cylinder. As soon as the grain begins to empty out ofthe cylinder G then the parts of the spring-scale D move again to theirformer positions, whereby the grain-cylinder G is raised to its normalposition, and, as the cylinder at the same time rotates, then the nextfollowing lug G is engaged by the hooks J and N of the lever J and thearm N, re spectively. The lugs G of the grain-weighing cylinder G aredisengaged from the hooks J and N as soon as the weight of the grain hasmoved the cylinder downward sufficiently so that the upper edge of thelug G is below the lower ends of the hooks J and N, and as the height ofthe latter can be regulated by the screw L it is evident that the grainin the respective compartments can be discharged when any desired weightis obtained. When the graiu-weighing cylinder G turns in the directionof the arrow a, as before described, then the respective lug G in itsupward movement strikes against the under side of the arm N, thuslifting the same until thelug G strikes against the hook J, after whichthe arm N drops downward again, so that its hook N engages .the otherside of the lug G and the lug N of the arm N, striking against the underedge of the lever J, prevents the further downward motion of said arm N.As the arm B can be swung sidewise, it permits of moving the grainweighing or measuring machine over a second wagon in case the first oneis filled without interrupting the passage of the grain from theelevator G into the chute P.

The arm B may be mounted on top of the thrashing-machine or on the sideor front of the same, or on a separate stand.

The machine may also be used for weighing coal or other substances, andemployed not only in thrashing-machines, but also in stores, warehouses,&c.

In regard to the use of both spring-scale and scalebeam, orbalance-weight, as it is used here, theobject is to accurately measurethe grain, and this can only be done by weight, as grain varies so muchin weight, by measure. Some grain falls short in weight, while othergrain overruns inweightbythemeasure. Now, to simply measure the grainthe spring scale or scale-beam, either one, would be sufficient; but tomeasure the grain accurately itmust be weighed, and the simplest meansof weighing it is by spring-scales. If spring scales alone are used, theweight of the measure comes on the scales and you have the weight of themeasure on scales over and above the weight of the grain, whereas inusing the scalebeam (or balance-weight) the weight of measure is takenfrom the scales, so the scales support and show only the weight of thegrain. In using the scale-beam (or balance-weight) in connection withscales I may always (by moving the weight back or forward,as the casemay be) have the scales evcnl y balanced. In this way the scales are inno strain except in weighing the grain and showing to the ounce how muchgrain is in measure. I find by actual test the apparatus operates muchmore accu- 3 rately and with much more satisfaction with bothspring-scale and scale-beam.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1 In a grain weighing and measuring machine,the combination, with a spring weighing-scale, of a counterbalancedgrain-cylinder connected with said scale, lugs formed on the sides ofsaid cylinder, hooks engaging said lugs, and adjustable lever-armscarrying said hooks, so that when the uppermost compartment of thegrain-cylinder is filled with a cer tain amount of grain then the lugsare disengaged from said hooks, substantially as shown and described.

2. In a grain weighing and measuring ma chine, the combination, with aspring-scale, of a counterbalanced grain-cylinder connected with saidscale and provided with four compartments formed by partitions securedto the sides of said cylinder, substantially as shown and described.

3. In a grain weighing and measuring machine, the combination, with aspring-scale, of 1 r0 a U-shaped frame connected with said scale, agrain-cylinder mounted in said U shaped frame and provided withcompartments formed by partitions secured to the sides of said cylinder,and links connected with the shaft of said cylinder, so as toprevent itfrom moving sidewise and endwise, substantially as shown and described.

4. In a grain weighing and measuring machine, the combination, with aspring-scale,of a counterbalanced grain-cylinder connected with saidscale and provided with compartments formed by partitions secured to thesides of said cylinder, and means, as described, for holding saidcylinder in a locked position until its uppermost compartment isfilledwith a certain amount of grain, as set forth..
